中文摘要：

采用单因素试验和正交试验,以总黄酮含量为考察指标,对影响总黄酮超声提取的因素进行研究。结果表明,花生壳中木犀草素的最佳提取工艺为30倍量70%乙醇,60℃下提取30min,其中乙醇体积分数对结果影响显著。

英文摘要：

To study the optimum extraction technique of luteolin in peanut shell by ultrasonic wave. The conditions for the extraction by ultrasonic wave were studied by single factor test and orthogonal test as guided by the content of luteolin in the extract. The optimum extracting condition was extracting 30 min at 60℃ with 30 times of 70% ethanol. Among all fac-tors, the ethanol concentration was significant. This procedure is convenient, appropriate and feasible.
